Thumela I-imeyiliIkhebuli yokusabalalisa ugesi noma amanethiwekhi amancane wokudlulisa ngokuvamile asetshenziswa njengokuphakelwa okuyinhloko Kumanethiwekhi Ezohwebo, Izimboni kanye nezindawo zokuhlala zasemadolobheni.Ifanele amasistimu amaphutha aphezulu alinganiselwe kufika ku-10kA/1sec.Ukwakhiwa okukalwe okunephutha eliphezulu kuyatholakala uma ucelwa.
Ibanga lokushisa:
Izinga lokushisa elincane lokufaka: 0°C
Izinga lokushisa eliphezulu lokusebenza: +90°C
Izinga lokushisa eliphansi lokusebenza: -25 °C
Irediyasi encane yokugoba
Amakhebuli afakiwe: 12D (PVC kuphela) 15D (HDPE)
Ngesikhathi sokufakwa: 18D (PVC kuphela) 25D (HDPE)
Ukumelana Nokuchayeka Amakhemikhali: Ngengozi
Umthelela wemishini: Ukukhanya (PVC kuphela) Kunzima (HDPE)
Ukuchayeka emanzini: XLPE – Futha i-EPR – Ukucwiliswa/Ukufakwa kwesikhashana
Imisebe yelanga kanye nokuchayeka kwesimo sezulu: Ifanele ukuchayeka okuqondile.
Ukwakha:
Kwenziwe Nohlobo Oluhloliwe AS/NZS 1429.1, IEC: 60502-2 namanye amazinga asebenzayo
Ukwakheka - 1 core, 3 core
I-Conductor - i-Cu noma i-AL, i-Stranded Circular, i-Stranded Compact Circular, i-Milliken ihlukaniswe
I-Insulation - i-XLPE noma i-TR-XLPE
Isikrini se-Metallic noma i-sheath - Isikrini se-Copper Wire (CWS), isikrini se-Copper Tape (CTS)
Izikhali - Aluminium Wire Armored (AWA), Steel Wire Armored (SWA), polyethylene (HDPE) yangaphandle - okunye
Osayizi Bekhebula le-MV:
Amakhebula ethu angu-10kV, 11kV, 20kV, 22kV, 30kV kanye no-33kV atholakala kububanzi obulandelayo bosayizi wezigaba (kuye ngokuthi amakhondaktha eCopper/Aluminium) ukusuka ku-35mm2 kuya ku-1000mm2.Osayizi abakhulu bavame ukutholakala uma ucelwa.
Ikhebula lamandla angu-19/33kV
